All patients are instructed at primary diagnosis and receive the Melanoma-Patient-Education-Package (MPEP), which consists of information on melanoma (KWF folder "melanoma") and additional instruction on self-examination. Data on type of recurrence (locoregional versus distant), the person detecting the recurrence, progression of recurrence at time of detection, the way the recurrence was detected (e.g., self-examination, accidentally, or at follow-up by physical examination or imaging) and information regarding treatment and further follow-up are collected at each follow-up visit and the outcomes are compared in both groups. Outcomes of independent questionnaires are also compared in both groups.
